Reduction, capsuloplasty and pelvic osteotomy in surgical treatment of inveterate congenital hip dislocation.

A new surgical technique is described for the treatment of inveterate congenital dislocation of the hip in patients aged between 6 and 26 years, i.e., when it is too late for simple surgical reduction of the dislocation and far too early for a total hip replacement. The technique consists of reduction of the dislocated head, followed by capsuloplasty for covering the femoral head with a cap, and pelvic osteotomy with medial displacement of the inferior (acetabular) part of the pelvis. In the 16 patients (17 hips) treated thus far, the follow-up shows that good restoration of hip function has been achieved.
